Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 339 Issued at 2200Z on 05 Dec 2009
IA.  Analysis of Solar Active Regions and Activity from  04/2100Z
to 05/2100Z:  Solar activity was very low.  No significant flares
were observed during the past 24 hours.  The visible solar disk is
spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 04/2100Z to 05/2100Z:
The geomagnetic field was quiet.  Solar wind observations from the
ACE spacecraft indicate the onset of a co-rotating interaction
region at around 06/0530Z.  Solar wind velocity and density
increased slightly with fluctuations in the IMF Bt and Bz.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled, with a slight chance for isolated
active conditions, for day one (06 December) due to a coronal hole
high speed stream.  Conditions are expected to be predominately
quiet for days two and three (07-08 December).
